Abstract

MÉTODO PARA DETERMINAR A RESISTÊNCIA ELÉTRICA LINEAR EM MODO DE CA DE UMA TUBULAÇÃO DE AÇO E DISPOSITIVO PARA IMPLEMENTAÇÃO DO REFERIDO MÉTODO. A presente invenção refere-se a um método para determinar a resistência elétrica linear em modo de CA de uma tubulação de aço, que compreende as etapas de gerar numa porção (4) da tubulação uma corrente induzida por meio de uma bobina de indução (6) centrada num eixo longitudinal (X-X) da tubulação e atravessada por uma corrente CA, sendo a bobina alojada num yoke (8) feito de material ferromagnético a fim de confinar o campo magnético a uma superfície pré-definida da porção da tubulação, medir a potência ativa dissipada pela porção da tubulação submetida ao campo magnético, medir a amplitude do campo magnético produzido, e determinar a resistência elétrica linear em modo de CA da porção da tubulação a partir das medições da potência ativa dissipada e da amplitude do campo magnético induzido. A invenção também se refere a um dispositivo (2) para a implementação de um referido método.
